FIREARM.

To aZZ whom it may concern:

Be it known that I, ARTHUR GREED WRIGHT, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented a new and useful Firearm, of which the following is a specification.

This invention relates to improvements in fire-arms and particularly relates to the production of a breech-loading fire-arm which has improved parts adding to the ease of manipulation, which is easy of manufacture,

and which can be readily assembled and put together.

The improvement relates to a means for limiting the rocking motion of the barrel on the forearm and consists in arranging a check joint or knuckle with which the flanges on the barrel can engage. This is applicable to either single barrel or double barrel shot guns or to multiple barrel guns which have two shot barrels and a rifle barrel attached underneath.

For the purposes of illustration, I have shown the improvements applied to a single barrel shot gun.

Referring to the drawing and in detail, Figure 1 is a partial side elevation and partial central sectional elevation with the gun open. Fig. 2 is a partial planview showing the construction of the front end of the frame. Fig. 3 is a partial plan showing the construction of top lever. Fig. 4 is a side elevation of the plate with the hammer and trigger assembled thereon and, Fig. 5 is a plan view of part of the operating mechanism between the locking bolt and the top lever.

The improved points of construction will be best understood by a detailed description of the mechanism.

Referring to the drawing and in detail, A designates the frame which carries the operating parts and secured to the rear of which is the stock B. The front or forwardly projecting part of the frame is slotted as at G and secured in the two walls thus formed is the pivot pin 10. The front end of the frame is shaped or cut away concentrically with the pivot pin 10.

D designates the barrel which has the usual depending lug 11 which fits in the slot C and the front face of which is grooved or cut away to engage the pivot pin 10.

E designates the forearm 'which is de- Specification of Letters Patent.

Serial No. 473,953.

tachably secured to the barrel in any desired way and the rear face of which is formed of metal shaped to engage the front end of the frame. The barrel is provided with side lugs 1212 preferably on both sides thereof which lie flat on the forwardly projecting part of the frame when the gun is closed. The upper faces of the two front walls of the frame are arranged below the top point of the circle on which the front end of the frame is shaped so that projections or lugs 18-13 will be formed on said upper faces against which the ends of the the lower front corners of the lugs l212 can turn around in close engagement with said walls until they engage the projections 1813. By this arrangement, an effective joint or check is provided so that as the barrel revolves on the pivot pin 10 in opening, the motion of the same will be positively limited. This way of constructing the joint for limiting the motion of the barrel is very economical and provides a limiting joint which is very free from wear.

A plate let fits into the bottom of the frame and is secured in place by horizontal pins or screws 15-15 and by a vertical screw 16 at the rear end of the frame. A trigger 17 is mounted on a pivot secured in said plate, the lower part of which trigger is normally pushed forward by a spring 18 held by a screw 19 in said plate. The hammer 20 is mounted on a pin 21 passed between ears formed on said plate. The trigger and hammer are provided with the usual projections and notches so that the hammer may be cooked and fired by the trigger and so that the hammer will rebound after firing to a position out of engagement with the usual firing pin which is arranged in the frame as shown in Fig. 1. A hub 22 projects up from the plate 14:. This hub has a hole bored through the same, which hole is screw-threaded.

A follower 23 engages the hammer 20 and the same has a rearwardly projecting shaft 24 on which is arranged a spiral spring 25 which thus forms the hammer operating spring. A bushing 26 is screw-threaded into the hub 22. The shaft 24L fits through the hole in this bushing and said bushing engages and forms the stop for the rear end of the spiral spring 25. The bushing 26 has its rear face slotted so that the same can be frame, the follower 23 is placed in position to engage the rear of the hammer with the shaft 24 extending through the hub 22, the spiral spring 25 is then pushed on to said shaft 24 from the rear thereof through the hub 22 and the bushing 26 is then screwthreaded into the hub 22 to form a support and guide for the shaft 24 and to adjust the tension of the spring 25. In this way these parts which are usually diflicult to assemble can be put together very rapidly and expeditiously. If it is desired at any time to adjust the tension of the hammer spring, all that is necessary is to remove the trigger plate and assembled parts from the frame and turn up the bushing 26.

The construction of the top lever and operating connections therefrom will now be described. A look or bolt 27 is pivoted in the frame and is arranged to engage the usual notch 28 cut in the rear of the lug 11 depending fro-1n the barrel D. The top lever 29 is pivoted on a screw 30 which is threaded into a slide 3l fitted in slots cut inside of the frame. The top lever 29 is provided with laterally extending arms 3232 on each side of the pivot screw 30 and the front end of the lever is cut away on a circle around the pivot screw 30. The upper part of the frame is cut away on a circle so that the front part of the top l'ever fits snugly therein and so that the arms 32-32 engage faces or projections 3333 on the frame. By this arrangement, when the top lever is moved either side of its central position, one or the other of the arms 32 will push on its face 33 and draw the pivot screw 30 to the rear and swing the lock. Thus the lever can be operated by pushing either to the right or the left. This makes the gun particularly adapted to either a right-handed or left-handed user.

The slide 31 is normally pushed forward by a spring 34 which is fitted on a small pin or shaft 35 extending to the rear from the slide and the rear of which spring is held by a cut-away screw 36 secured in the frame. The slide is connected to'the oscillating locking bolt by means of connecting rods 37, the ends of which engage pins 38 and 39 inserted respectively in the slide 31 and the oscillating locking bolt 27. By moving the top lever either to the right or the left the bolt 27 is unlocked to allow the barrel to be rocked or.turned up for recharging. The spring 34 normally forces the bolt 27 forward to'engage the barrel lock 11 so that the barrel can be snapped back to operative position. Thus by these features of construction the manufacture, assembling and manipulation of the firearm is improved.

The details and arrangements herein shown and described may be varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim and desire to secure by Letters-Patent is,

1. In a fire-arm,.the combination of a slotted frame, a pivot pin extending across the slot, and a barrel pivoted on the pin and having an integral side lug above and at the rear of said pin, the end of the frame being cut away at the top to leave an upwardly extending projection against which the side lug engages to limit the downward rocking movement of the barrel on the pivot 3m. l 2. In a fire-arm, the combination of a frame, a pivot pin secured therein, the end of the frame having a top point which is slightly above the wall of the frame so as to leave an upwardly extending projection, and a barrel pivoted on the pin and readily removable from the frame and provided with an integral side lug, theforward end of which engages said projection to limit the downward rocking movement of the barrel.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses. I
